Gene Expression in Endogenous and Transplanted fat was measured by real-time qRT-PCR. Analyses of fat-related molecules, such as PPARγ, FAS, leptin, adiponectin, resistin and RBP4, showed that: 1) all transplanted fat grafts (in the VIS-VIS, SQ-SQ, and SQ-VIS transplantation groups) express PPARγ and FAS mRNA levels that are not significantly different from that of endogenous VIS or endogenous SQ fats in the sham group; 2) adding more fat of the same depot (VIS-VIS or SQ-SQ) does not change gene expression levels of the first four fat genes analyzed except for resistin and RBP4 in the VIS-VIS group; and 3) adding SQ fat to the VIS cavity lowers mRNA levels of leptin, adiponectin, resistin and RBP4 in comparison to levels in the endogenous VIS and SQ fats in the sham group.
